Tune from Mike at 5Star Tuning the sound is still there but just a little less and shorter.Now Mike told me to give the PCM its learning abilities for a little while. Maybe it goes completely away in some miles of driving and on and offs of the truck.What you think it might be?Header noise?I don't think its a leak since the it only does the sound under regular or hard acceleration and only at certain point where you accelerate in a high gear where the truck needs some effort to come to certain speed.Sent from my SAMSUNG-SGH-I337 using Tapatalk</blockquote>
